MAME OS X displaying black screens for games

[FlightSuit]

Hi everybody, long time no post!

I'm hoping you can help me with a problem that recently developed with MAME OS X:

When I launch a game, I can hear the game running, but the game window just displays a black screen.

When I first choose the game from the list of available ROMs, its start screen displays for a second on the right-hand side of the menu screen, but once the game is running, I get the black screen.

I had not changed anything in MAME OS X's preferences, or under its "view" or "effects" dropdown menus, but maybe I need to fiddle with something there?

This is MAME OS X version 0.135, running under MacOS Mojave 10.14.6.

 

I did try telling MAME OS X to audit my roms, but that does not seem to have helped.

The Read Me file inside my ROMs folder doesn't say which version of the rom set I have, but it's pretty old. That shouldn't matter, though, because I have not updated MAME OS X at any point, right?

Thank you in advance for any help you can provide!

By Jove, you have solved my problem! Switching to Open GL in my video preferences did the trick!

Now then, my keyboard mapping seems to have possibly changed, and I can't find a screen or preference for changing which keys correspond to what buttons on an arcade cabinet. Could you remind me, please, where and how I can change that?

Thank you!

Been a while, had to look it up.  Thankfully the Mac mini that drives my TV is on an older release of macOS that still supports 32-bit software.

 

 

Hitting TAB when viewing the list of games just takes you to the play count:

Oh! Right, right, right! Thank  you again! You are a treasure!

Between MAME OS X and Quicktime Pro 7, I am coming to terms with the fact that I must never update my Mac beyong MacOS Mojave, because I don't want to ever break compatibility with this software.

I would be so screwed if I had to find a proper replacement for MAME OS X and then seek out a current ROM set.
